Resizing

[Daniel Rottschäfer]

Hello,

i created a table in which the size will be automatically adjusted if I check or uncheck an item at the chart-legend.
How do I do that?

Best regards

Daniel

I have a additional question:

How do i get the max value from the x- and y-axis?

Hi Daniel,

Thanks for showing interest on Syncfusion products.

The below code is used to check all the legend items in the chart legend by setting to true.
To uncheck set it to false.
this.chartControl1.Legend.VisibleCheckBox = true;

The below code is to check each legend item individually by setting to true.
To uncheck set it to false.
this.chartControl1.Legend.Items[0].VisibleCheckBox=true;

The below code is to find the max value for X axis and Y axis.

this.chartControl1.PrimaryXAxis.VisibleRange.Max
this.chartControl1.PrimaryYAxis.VisibleRange.Max

Please let me know if this helps.

I had something else in my mind when i asked the questions.

I want the chart automatically to resize if i uncheck an legend item. The Max X- and Y-Axis Values should be the max Value of the shown series.

How can i do that?

And how do i get the maxvalue of any series without counting themselves when filling the data?

Hi Daniel,

The chart resizing can be done by using the legend items Checked changed event.
Below mentioned example code will perform the resizing of the chart control.

Example code:

this.chartControl1.Legend.Items[0].CheckedChanged += new EventHandler(Form1_CheckedChanged);

void Form1_CheckedChanged(object sender, EventArgs e)
{
      if (this.chartControl1.Legend.Items[0].IsChecked)
      {
          this.chartControl1.Width = 700;
          this.chartControl1.Height = 700;
      }
      else
      {
          this.chartControl1.Height = 200;
          this.chartControl1.Width = 600;
      }
}

The max value for the shown series can be found out by using the below code snippet without counting the data.

Code snippet:

this.chartControl1.Series[0].Summary.MaxX
this.chartControl1.Series[0].Summary.MaxY

The below mentioned code snippet is to set the max value of the given series to the max X and Y values of the axes.

Code Snippet:

this.chartControl1.PrimaryXAxis.Range.Max  = this.chartControl1.Series[0].Summary.MaxX;
this.chartControl1.PrimaryYAxis.Range.Max =  this.chartControl1.Series[0].Summary.MaxY;

Please let me know if this meets your requirement.
